Continuous and quantitative electroencephalography changes of case 1. a Baseline EEG shows generalized slowing with a lateralized slowing in the left hemisphere generalized. b black box indicates the change in QEEG where rhythmicity in the right then left hemisphere drops out (open arrows) also noted, decrease in asymmetry of the left hemisphere (black arrow) and increasing in burst suppression ratio (blue arrow). c diffuse suppression
